I would like to brag and say that I snapped the lockring threads off of my hub with my amazing leg power but I'm sure it is due to a multitude of other things which EXCLUDES my leg power. My most recent build is my first track-specific frame (not a road conversion) and I used to always ride with a brake on my other bike but out of my excitement to try my new bike I rode it without a brake and became obsessed with the simplicity.
On my way home from work I wanted to see how fast I could stop from a full sprint but when I smashed the pedals I suddenly found myself coasting and my pedals not turning

. The passion that I have had all week about never wanting brakes again was gone in a split second.
So my question, are there any hub/lockring combinations that can take abusive stops repeatedly without failure? I don't want anything that costs more than my wheelset (DP18's) I just want a cheap and presumably heavy hub that would be impossible to strip or I will have to start riding with a brake again.
Thanks guys.

My set up was an aluminum origin 8 hub, steel lockring, Eighthinch cog which was tightened using the chain and cranks, the lock ring was hammered tight with a blunt metal punch. When I went to buy a tool for the lockring my local lbs (also my mtb friends, NOT fixie riders) told me to just use a hammer/flathead, do you guys think this may have lead to the failure?
